This is a proof of concept for a simple Node.js server that splits, stamps and distributes chunks to multiple Bee nodes.

Setup

Run npm install.

Run npm run build.

Docker images

https://hub.docker.com/r/blossomlabs/chunkstorm/

Environment Variables Configuration

Create a .env file in the project root directory based on .env.example.

Required Variables

• BATCH_ID: The Ethereum batch ID for stamping chunks (hexadecimal string)
  • Format: 0x followed by 64 hexadecimal characters

Authentication (One of these options is required)

• Option 1: Private Key

  • PRIVATE_KEY: Your Ethereum private key for signing stamps

• Option 2: Keystore File

  • KEYSTORE_PATH: Path to your Ethereum keystore file
  • KEYSTORE_PASSWORD: Password to decrypt the keystore file

Optional Variables

• BEE_ENDPOINT: URL of the Bee node API

  • Default: http://localhost:1633

• PORT: Port number for the Chunkstorm server

  • Default: 3050

• STAMPERSTORE_PATH: Directory path to store stamper binary files

  • Default: . (current directory)

Use

Start the server with node dist.

Run the benchmark with node dist/perf.js.

Info

The benchmark uploads 45 randomly generated 128KB files to the server. It should finish in less than 12 seconds.

The current stamper in Bee-JS finished in 40301ms.

This was brought down to 21467ms by switching to an optimized stamper.

Another 2.5X speedup could be achieved by a faster secp256k1 signature implementation.
